Abstract

Abstract The objective of the study was to analyze the three typical elements of gauging in small channels and ditches for irrigation and to generate mathematical models that govern their hydrodynamic behavior. In the first stages, the discharges between 0 L/s and 10 L/s were determined, the number of measurements was nine for each element, with a total of 54 measurements, and finally the calibration equations, and the curves characterizing the flow meters were generated in the hydraulic bench of the laboratory. The equations and calibration curves were established to determine the flow rate in L/s as a function of the height of the tie rod in mm. The simulation of flow in the gauges was due to flow behavior under supercritical regime. La medición del gasto es muy práctica y rápida, además la precisión de las medidas depende directamente de la nivelación correcta de los instrumentos, lo que confirma Pedroza (2012) en su estudio realizado en función del análisis de Standard Test Method for Open Channel Flow Measurement of Water with Parshall Flume de la American National Standard.
